The price is per pair! The price of Sonicaps have just gone up and it caused a slight increase in the cost of this upgrade. This kit includes everything you need to correct a number of issues and take this speaker to another level across the board. Please see the videos and measurements in the accordion below. The kit includes all new parts, a set of tube connectors and new wiring.

I know parts make a difference. I was really blown away after doing this upgrade. Wow! Danny was right on this next level. I would say 30% increase. I didn’t realize the speaker sounded like they had a harshness to them. More detail it’s like they opened up. They don’t have a harshness to them anymore I didn’t realize they had. I did them one at a time so I could listen to the difference…In my industry quality parts, always make a difference and once again it did. Here’s the fax hearing is believing it bring the speakers up the next level, plus it was a lot of fun to do, I own a couple of auto body shops and the biggest problem was,all the guys wanted to be involved in doing it lol… I’m looking for more speakers just to upgrade now! Great job GR research. Looking forward to what you come up with next.👍🏼💯
